It seems that Chinese manufacturer OPPO is really trying to build up the hype around its upcoming Find 7 smartphone. This close to the scheduled unveiling, the company has started sending out invitations to Chinese media and bloggers that isn't what you'd call conventional. OPPO is hardly the first one to send out an unorthodox format for an invitation, and it's unlikely that it will be the last. Rival manufacturer Vivo also played up its XPlay 3S event by utilizing a bit of Augmented Reality (AR) in their invitation. OPPO's version is somewhat not as sophisticated, but it isn't less fancy and definitely more bulky.(via http://androidcommunity.com/oppo-sends-out-gimmicky-invitations-for-find-7-event-20140311/)
